Without getting bogged down in the linux display-manager holy war, I use the i3 window manager every day at both home and work since... well it's a great display manager!
Additionally, its design makes it easy to extend.
A small gripe
By default i3 shows a bar at the bottom of the screen with the workspaces (the i3-bar) where each workspace is identifed by a static number. This is useful but requires you to remember what apps are running in each workspace... which is too much for my perforated memory.
I wrote a little script to update the workspace name dynamically based on what apps are running in it, and since icons are much more succint than a concatenated list of app-names you can also configure it to show an icon instead of a particular app name.
There is an example i3-bar image at the top of this article, more screenshots are below.
